The successful formula of rubber conveyor belt often passes through many experiments and multiple variables. Whether the formula is reasonable and whether the physical and mechanical properties of vulcanized rubber meet the requirements. First of all, through the laboratory test to make a close. On the one hand, all kinds of physical data are accurate and reliable. On the other hand, the traditional research methods are needed.
The main feature of the "three square" design is a conscious addition of a square between the first and the third squares. Improved the traditional research methods. The addition of second squares provides a theoretical basis for design. Reduce the blindness and workload of the test work. It is an effective method to find the relationship between structure and performance. Because of the mechanical properties and processability. Mainly depends on the microstructure of rubber tape. At present, many advanced instrument testing methods. Can accurately determine its microstructure, provide a more accurate basis. Nuclear magnetic resonance (NMR), for example, can be used to study the degree of crosslinking of rubber and the extent to which rubber molecules adsorbed on the surface of the filler. So as to estimate the filler reinforcement. Thermal analysis of vulcanization process with DSC. The difference of reaction type and reaction rate can be judged from the change of the thermal effect of vulcanization reaction. The crystallization orientation analysis of vulcanized rubber or rubber with X ray diffraction method can. The dynamic viscoelasticity of rubber can be analyzed by DMA, provides an important basis for the design of damping products, production and sales of rubber belt manufacturers, infrared spectroscopy, ultraviolet spectroscopy, gas chromatography, thin layer chromatography was used to determine the cracking of instrument rubber structure, method of phase structure and phase contrast microscope etc. study on polymer by electron microscopy and is currently used.
The determination of the distribution of the complexing agent for the production belt in the mixture is closely related to the distribution of the dispersant. Check whether the mixing of raw materials is even. Direct and quantitative determination by electron microscopy and optical microscopy. Physical mechanical properties, extrusion swelling rate, viscosity and resistivity methods are also available. It can also be used to measure the pressure instrument and power integrator. This project is very important to the study of machining performance. It is more practical and valuable for the quality management of the factory. Have a profound impact on the quality control of rubber processing.
